Taw qhia rau tus qauv ntawm kev siv Digital Oscilloscope los sim hloov fais fab hloov fais fab
Oscilloscope thiab lub zog ntsuas
Rau cov neeg tau ua dhau los siv oscilloscopes rau kev ntsuas siab dua, ntsuas hluav taws xob yooj yim vim nws qhov tsawg zaus. Qhov tseeb, muaj ntau cov kev sib tw hauv kev ntsuas hluav taws xob ntsuas uas cov neeg tsim hluav taws xob siab yeej tsis tas yuav luag.
Qhov voltage ntawm tag nrho cov hloov pauv yuav yog siab thiab 'ntab', lub ntsiab lus nws tsis yog av. Cov mem tes dav, lub sijhawm, zaus, thiab lub luag haujlwm ntawm lub teeb liab yuav sib txawv. Nws yog qhov tsim nyog yuav tsum tau raug kom raug thiab txheeb xyuas cov nthwv dej, thiab ntes cov anomalies hauv cov nthwv dej. Qhov yuav tsum tau rau qhov oscilloscope no nruj. Ntau qhov kev sim ua - xav tau ib qho kev sim ua ntej, kev ua haujlwm sib txawv, thiab cov kev sim tam sim no ib txhij. Qhov ntsuas yuav tsum muaj lub cim xeeb loj los muab cov chaw kaw cia rau lub sijhawm ntev ntev-zaus cov txiaj ntsig tau txais. Thiab nws yuav xav tau cov cim sib txawv nrog cov hluav taws xob sib txawv hauv ib qho kev kawm.
Cov qauv qhia ntawm kev hloov lub zog fais fab
Lub ntsiab hluav taws xob DC cov khoom siv hluav taws xob hauv feem ntau cov xov xwm niaj hnub no tau hloov kho fais fab), uas yog cov muaj peev xwm ua tau zoo tiv thaiv tau zoo. Lub zog hluav taws xob txoj kev ntawm ib txwm hloov fais fab fais fab suav suav nrog cov khoom sib zog, cov khoom siv nquag, thiab sib nqus. Hloov cov khoom siv hluav taws xob yuav tsum txo qis kev siv cov khoom siv poob zoo xws li cov khoom siv tsis zoo xws li hloov chaw tsis muaj peev xwm xws li hloov chaw transistors, capacitors, thiab khoom sib nqus.
Lub Windaging fais fab khoom siv kuj tseem muaj kev tswj hwm ib feem xws li Pulse dav qauv kev tswj hwm, thiab cov lus pom zoo yuav muaj nws cov khoom siv fais fab. Daim duab 1 yog daim duab txheej txheem sib kho ntawm lub tshuab hloov hluav taws xob sib hloov, suav nrog cov khoom siv hluav taws xob, nrog rau cov khoom sib nqus.
Hloov hluav taws xob hluav taws xob siv hluav taws xob thev naus laus zis xws li Hlau Oxide Cov Nyias (Mosfets) thiab Ripulated GATE Bipolar tistors (iGBTS). Cov cuab yeej siv no muaj lub sijhawm hloov luv luv thiab tuaj yeem tiv taus hluav taws xob voltage tsis ruaj khov. Sib luag ib sis yog qhov tseem ceeb yog tias lawv haus lub zog me me, nrog kev ua haujlwm siab thiab tsawg cua sov, txawm tias nyob hauv lub xeev qhib. Hloov pauv cov khoom siv sib tw txiav txim siab tag nrho cov kev ua tau zoo ntawm kev hloov cov khoom siv hluav taws xob. Cov ntsuas hluav taws xob tseem ceeb nrog: Hloov chaw poob, hluav taws xob poob qis, muaj kev nyab xeeb thaj chaw ua haujlwm, thiab lwm tus.
